BURGLAR-PROOF SAFE.

SPECIFICATION forming part of Letters Patent No. 405,564, dated J une 18, 1889.

Application filed December 24:, 1888. Serial No. 294,500 (No model.)

To all whom, it may concern,.-

Be it known that I, PHINEAS F. KING, a citizen of the United States, and a resident'of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Burglar-Proof Safes, of which the following is a Specification.

My invention relates to that-class of burglar-proof safes in which the circular door is drawn to the closed position by spiral, cam, or screw-thread connection between the door and its jamb and held in the closed position by a time-lock. Its object is to prevent any strain being` brought upon the time mechanism by thoughtless or evil-disposed persons bearing upon or manipulating the door-handle. This object is accomplished by the Ineans herein shown and described, whereby the handle is wholly disconnected from the door proper until the predetermined time when it is to be released from the time mechanism and again coupled to the door by the person having the key or combination of the handle coupling and uncoupling the lock.

The invention will be first fully described in connection with the accompanying drawings, and will be particularly referred to and pointed out in the claims.

Referring to the drawings, in which like parts are indicated by similar referencelet ters wherever they occur throughout the various views, Figure l is a front elevation of a safe provided with my improvements. Fig. 2 is a vertical section of the same, taken through line oc of Fig. l. Fig. 3 is an inside plan view of my door attachment disconnected froin the door.

The safe-body A, with its circular front opening to receive the door B, and the-cranehinge Cfor hanging the door, form no part of this invention, and will not therefore be specifically described. It is sufficient to state that the door is drawn to the position shown in Fig. 2 by a screw-thread b upon the inner part of the door engaging threads in the ring a, which is secured upon the inside of the front wall, the door being held from turning by the bolt or dogging device of a time-lock (not shown) in the usual manner. The whole of my improvements are connected to the outside of the door, and will now be described.

Secured to the front of the door, so as to form, in fact, an integral part of it, is a ring D. This ring has an outwardly-progecting flange d around it to confine the ring E, which 5 5 is fitted to allow the door B and ring D to turn freely, while the ring E is rigidly held from turning by the pintles or pivots c, which are passed through the arms of the cranehinge and into the edge of the ring E. The 6o ring D has also an inwardly-projecting annular flange d to confine the circular box F, which is fitted to turn freely within the ring D.

Upon the front of box F are secured two Standards g, in the outer ends of which is secured the handle G, by which the door is rotated to open and close it.

Within the box F and secured to it is a lock H, the bolt h of which, when shot out, is just long enough to pass through the edge of the 7o and to be forced into a recess in the inner rim 7 5 of the ring E by the bolt h of the lock H. The bolt I is provided with a spring z', which is also recessed into the ring D. The pressure of the spring is exerted to force the bolt I inwardly through the bolt-slot in the rim of box 8o F when the bolt of lock H is retracted, and thus couple the box F, ring D, and of course the door, so that they must move together. This inward movement of bolt I also uncouples the rings D and E, so that the door may be revolved by the handle if the time-lock guard be thrown off and withdrawn and swung around upon the pivots c. Thus, when the door is closed and bolt I forced to the position shown in Fig. 3 by the lock-bolt h, rings 9o D and E and door B are locked together and prevented from being turned by the hingepivots c,wl1ile the box F may be freely turned, the bolt I riding around upon the periphery of the box F without affecting the door, and 9 5 consequently no strain could be brought upon the time mechanism; but when the bolt 7e of lock His retracted the spring-actuated bolt I will be drawn inward so soon as the Slot in box F comes opposite to it and couple the door Ioo to box F, and at the same time release it from rigid connection with ring D.

I have shown a common key-lock for coupling and uncoupling the handle and door-carrying ring E and the door; but it is obvious that a combination-lock may be employed in the same position and for the same purpose, and it is also obvious that many merely inechanical changes may be made in the particular features 0f the sate, door, and connections Without departing from the spirit and scope of my invention.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a safe having a circular door arranged to be closed by rotating it and secured by a lock preventing its rotation, the combination of a ixed ring secured to the front of the door, a door-carrying ring for connection with the hinge, a circular case Within the vfined ring for the reception ot a lock and attachment of the handle for rotating the door and having its edge slotted to pass a lock-bolt, a lock Within said case so arranged that its bolt will pass through said slot, a coupling-bolt arranged to slide in the iXed ring and to be forced in one direction by the lock-bolt, a spring to force the coupling-bolt in the opposite direction, whereby the door-carrying ring is locked to the door and the handle and lock are disconnected when the bolt of the lock is shot out and the handle coupled to the door7 and the door-carrying ring disconnected wh en the lock-bolt is retracted.

2. A handle connecting and disconnecting device for circular doors for safes, consisting of a ring rigidly connected to the door-front, a loose ring around said rigid ring to connect to the hinge-pivots and support the door, a circular box or look-case fitted to turn Wit-hin said ring, a handle connected to said box, a spring-actuated bolt recessed in the rigid ring and arranged to couple y either the outer door-carrying ring or the inner lock and handle carrying case, and a lock Within said case, substantially as and for the purpose set forth.

3. The combination,substantially as specified, of the safe-body A, having a 'circular door-opening, the interiorly-screW-threaded ring a, secured upon the inner front Wall and surrounding the door-opening, the circular door B, having upon its inner end the screwthreaded part h, the ring D, having iian'ges d d secured to the door-front, the ring E,titted around the ring D and confined by its iange d, the circular box F within ring D and confined by its flange d and having the slot-ted bolt-opening, the lock H, having bolt h to protrude through the opening in box F, and the spring-actuated bolt l.
